I'm... not really happy with the result, but at least I know what to do next.
So, after I found out that I used too large canvas, now I also find out the pose is too stiff. Like, I should have taken time on doing each work. I need to slow down a bit to study my mistakes and correct them.
I will seriously need to take my time on this. Probably have to split my time to do many things at once. Probably on meme, strip comic, and studying posing, so I won't be too focusing on one thing too much.
